A Question of Evidence: The Casebook of Great Forensic Controversies, from Napoleon to O.J. - Hardcover

The science of forensics has evolved into a well-established, indispensable crime-solving tool-and yet there have been times when forensic techniques have failed to completely resolve certain trials. Whether shoddy lab work or faulty evidence collection is to blame, these perplexing and fascinating cases have long been the subjects of heated discussion and no small amount of disagreement.

From the still-contested death of Napoleon Bonaparte to the never-ending speculation that surrounds John F. Kennedy's assassination, A Question of Evidence takes a probing look at fifteen of the most contentious cases in history-cases that are still being fought over today. Popular science author Colin Evans demonstrates how everything from misgivings and bitter feuds to strongly held passions can sometimes vanquish the best that science has to offer.

Each case is packed with controversy, from botched experiments and blatant evidence tampering to hubris and just plain stubbornness. Even the greatest experts are far from infallible-and even the most impressive testimony may owe more to personal gain than it does to impartial analysis. Evans examines the scientific sleuthing and slip-ups in the investigations of such defendants as:
* Alfred Packer-a self-confessed cannibal who nevertheless may have been the tragic victim of a flawed justice system
* Donald Merrett-an eighteen-year-old who defrauded his mother-but was he her killer?
* Lindy Chamberlain-mother of the infamous "Dingo Baby"
* Jeffrey MacDonald-the man accused of slaughtering his family in the astonishing case recounted in Fatal Vision
* Sam "The Fugitive" Sheppard-the only person in American legal history to have been convicted, acquitted, and then convicted again for the same murder

A Question of Evidence proves beyond a reasonable doubt that the truth can be as elusive in death as it is in life.

Lee Harvey Oswald.

Samuel Sheppard.

O. J. Simpson.

The infamous cases surrounding these individuals seem to be forever clouded by doubt and suspicion. They are among the many cases from around the globe that resist a satisfyingly scientific conclusion and, to some, remain more open than shut.

In A Question of Evidence, the author of The Casebook of Forensic Detection details some of the most vexing forensic controversies of all time. From the Turin Shroud to the death of Napoleon Bonaparte to the assassination of JFK, Colin Evans lays out the conflicting medical and scientific evidence of each case and shows how it was used or mishandled in reaching a verdict. You'll discover why even the most efficient crime lab and expert testimony can still fail to resolve a difficult case to everyone's complete satisfaction.

As absorbing and suspenseful as the most gripping mystery novel, A Question of Evidence will have you pondering the verdicts long after the last gavel comes down.
